This article is about a/an set of alternate forms in Kamen Rider Den-O.
Plat Form (プラットフォーム Puratto Fōmu) is the default form of the time train riders before the Aura Armor forms. It is much weaker than their other forms.

Ryotaro Nogami is the only rider that has spent a significant amount of time in this form, due to his meek personality initially being too weak to form Aura Armor.
